Theresa May is fighting for survival today after a draft divorce deal with the European Union provoked the resignations of senior ministers and open mutiny in her party.

Brexit minister Dominic Raab resigned on Thursday over her deal, sending the pound tumbling. Mutinous lawmakers in her own party openly sought to challenge her leadership and bluntly told her that the Brexit deal would not pass parliament.

May, who has vowed to stay on as prime minister, was asked by a caller on an LBC radio phone-in this morning to “respectfully stand down”. She did not immediately address that part of the caller’s question.

The 48 letters from Conservative lawmakers required to trigger a vote of no confidence in Prime Minister Theresa May have been submitted, the editor of Brexit Central said earlier today, citing a single source who he said was always previously reliable.
